Abstract

PURPOSE:To eliminate the loss of the positioning time due to the reciprocating motion in the conventional control method to perform positioning in a short time, by switching the motor from the high-speed motor to the low-speed motor by the maximum speed reduction point, which is operated preliminarily before the start of positioning, to perform positioning. CONSTITUTION:The position before the start of positioning is denoted as point A, and the target position is denoted as point B, and the position where the speed is switched from the negative- direction high speed to the negative-direction low speed, namely, the fixed speed reduction point is denoted as point C. The position where the low-speed motor is stopped, namely, the stop point is denoted as point D, and the positioning start position where the high-speed motor becomes the maximum speed instantaneously and is switched to the low-speed motor is denoted as point E, and the position for switching from the optimum negative-direction high speed to the negative- direction low speed which is operated by values at points A, B, C, D and E becomes point C. In respect to the operation, the device is moved to point C in the negative-direction high speed; and when the device passes point C, the device is moved to point D in the negative-direction low speed; and when the device reaches point D, the low-speed motor is stopped to move the device to point B by inertia, thereby completing positioning.
